I'm a creator of an app that integrates with OneNote API via Microsoft graph SDKs for Android/iOS. Several of my users reported that the new OneNote notes stopped syncing with the app (hundreds more affected by this).
I've been debugging this. And I can confirm that OneNote API does not return new pages. To reproduce:
1) create some new notes
2) go to Graph Explorer (https://developer.microsoft.com/en-us/graph/graph-explorer/)
3) user basic query (https://graph.microsoft.com/v1.0/me/onenote/pages)
New pages are not being returned, even after a few days. My app uses the same endpoint to get the latest pages.
I would appreciate it if someone could look into this. I can provide all the data needed to debug.
Side Note: The official OneNote app sees the notes correctly (on both iOS and Android).
UPDATE
MS Graph Explorer started showing notes which were added 5 days ago (our users report the same). So it seems like a very long delay in propagating the data (the official OneNote app syncs new pages almost instantly). It would be great to get a response from OneNote team on this.
Looks like similar issue was reported 2 years ago
Is there a way to overcome lag between changes in OneNote client and API results?
Tested with "FavorDataRecency" header but still no results.
UPDATE 2 (05.02.2020) The new notes stopped showing up completely (tested even after a few weeks time). What is interesting is that if I create a new section the section pops up from the API endpoint immediately (just name, without notes).
